The word radiation is, to the lay person, a scary word. Radiation is the stuff that 1960s school children were taught to climb under their desks to avoid, and what prompted Cold-War-terrified Americans to build backyard bomb shelters. Radiation is the stuff that leads meltdowns at nuclear power plants to contaminate the ocean and make land uninhabitable for hundreds of years.
“It’s because WiFi is just a low frequency sound wave.” For me, the jury is still out concerning the link between WiFi and sleep disturbance. But I’m sorry, you are wrong about WiFi being a low frequency sound wave. It is a radio wave, i.e. electromagnetic, and it runs at 2.3 GHz and/or 5 GHz, which cannot by any stretch of the imagination be described as low frequency.

If you have invested in the latest iPhone, or you are rocking a super-cool Samsung Galaxy S7 or S6, you don't want to wrap it up in an ugly case that hide's the phone's designer charms. Shop hot brands such as OtterBox and LifeProof, and ensure your phone has optimum protection without sacrificing style. Sellers on eBay have a wide inventory of top-name brands in bran new condition, making it possible to pick out a case that is a true reflection of your fashion-forward personality.

I have treated patients with cancer for over thirty years as a board-certified radiation oncologist and I am familiar with every carcinogenic agent known to man. I'll tell you with absolute certainty that radio waves cannot harm you (unless perhaps you were in the path of a multi-megawatt microwave beam, in which case they might cook you. But as far as I know, there is no likelihood that this danger even exists).

Participation bias, which can happen when people who are diagnosed with brain tumors are more likely than healthy people (known as controls) to enroll in a research study. Also, controls who did not or rarely used cell phones were less likely to participate in the Interphone study than controls who used cell phones regularly. For example, the Interphone study reported participation rates of 78% for meningioma patients (range among the individual studies 56–92%), 64% for glioma patients (range 36–92%), and 53% for control subjects (range 42–74%) (6).

A study by the Corporate EME Research Laboratory and Motorola Florida Research Laboratories tested 9 different cell phone radiation shields, 5 of which claimed to block 99% of cell phone radiation. The other 4 shields tested claimed to emit a reverse radiation that would cancel out the harmful radiation from cell phones. The study found that all of the radiation shields had no effect on the amount of radiofrequency radiation a cell phone user is exposed to from their phone.[2]
The wireless industry has sought to downplay concerns about cell phones’ safety, and the Federal Communications Commission has followed its example. In 1996, the FCC established cell-phone safety levels based on “specific absorption rate,” or SAR. Phones were required to have a SAR of 1.6 watts or less per kilogram of body weight. In 2013, the American Academy of Pediatrics advised the FCC that its guidelines “do not account for the unique vulnerability and use patterns specific to pregnant women and children.” Nevertheless, the FCC has declined to update its standards.30
We can’t stop people from misleading others for profit, but we can respond to their nonsense. We’ve received more than a few letters here at How-To Geek from concerned readers asking if they should turn off their wireless equipment when not in use, or get rid of it altogether. So we’ve decided to add a reasonable voice to the conversation so, hopefully, people will find this and breathe a much deserved sigh of relief.

The purpose of this study was to investigate the oxidative damage and protective effect of garlic (daily 500 mg/kg during study period) on rats exposed to low level of electromagnetic fields (EMF) at 2.45 GHz Microwave radiation (MWR) for 1 h/day for 30 consecutive days. Researchers concluded that low level EMF at 2.45 GHz MWR increases the DNA damage in both brain tissues and plasma of the rats whereas it increases protein oxidation only in plasma. They also be argued that the use of garlic decreases these effects.

The answer is yes, it can. Will it always make people sick? No. Dr. George Carlo explains that there is most definitely a biological response to what he refers to as Information Carrying Radio Waves (ICRW-energy fields from many wireless devices). When you're exposed to ICRW a process of adaptation and compensation occurs in your body. He has a great program that can help people adapt.

Because of inconsistent findings from epidemiologic studies in humans and the lack of clear data from previous experimental studies in animals, in 1999 the Food and Drug Administration nominated radiofrequency radiation exposure associated with cell phone exposures for study in animal models by the U.S. National Toxicology Program (NTP), an interagency program that coordinates toxicology research and testing across the U.S. Department of Health and Human Services and is headquartered at the National Institute of Environmental Health Sciences, part of NIH.
"Love it...In love...This case works as advertised, no pocket dialing and everything shows through the case clearly as expected, this is the second case of this type I have purchased and both although a bit pricy at $59 work to perfection....Love the fact that this case gets it's power wireless(y) from the phone rather than a battery within the case itself which would wear out rather quickly."
Wifi routers can and have still been able to emit frequencies even while turned off. So just, beware of that. I completely got rid of my wifi router at home. It’s to that point. Also save on the cable bill now so it’s a win win. Nope. Don’t need all that radiation just to have a “stronger” Internet connection for all my wireless devices! Haha, so u know what they did? The cable company cut off some channels that were in my package. To try and make me call back and pay to have extra channels. That’s why they ask you, what channels do you watch ? Try try to up sell sell sell you to get you to watch TV all day while your body is getting radiated all day from your wifi. Wether your hyper sensitive to it or not, like some of us are greatly effected, your health is still being effected.

Like any investment worthy of protection, cell phones are no exception. Amazon carries a wide variety of cell phone cases and covers to meet your needs. Whether you’re in the market to find an accessible armband to use your cell phone during workouts, or a battery charger case to boost the power on your cell phone’s dying battery life, Amazon offers a wide selection so you can choose the case or cover that best fits your lifestyle.

The 5.93-inch screen is massive, with plenty of room for most games and movies. The Kirin 659 processor is powerful and capable of standing with any other similarly priced phone on the market. The 3,340mAh battery is long-lasting, and kids who like to take snaps (most kids have an Instagram game that’s on point) will appreciate the extremely good dual-sensor camera suite on the back of the phone. The metal unibody is strong and should be fairly durable, and since it’s running Android there are tons of great parental control apps out there. The only real downside is that Honor’s phones do not support Verizon or Sprint, so if you’re on a family plan with either of those two, this isn’t your best choice. Otherwise, the Honor 7X is a fantastic budget smartphone that kids will love.

Thirty-two rats and their forty newborn offspring were divided into the following four groups according to the type of EMR exposure they were subjected to: the control, 900, 1800, and 2450 MHz groups. Each experimental group was exposed to EMR for 60 min/day during the pregnancy and growth periods. The pregnant rats were allowed to stand for four generations (total 52 weeks) before, plasma and uterine samples were obtained. During the 4th, 5th, and 6th weeks of the experiment, plasma and uterine samples were also obtained from the developing rats. [The electric field density was set at 20 dB and 11 V/m in order to obtain 0.1 W/kg whole-body average specific absorption rate (SAR).]
Dr. Carlo, wrote a Medical Alert ten years ago. He cautioned people with EMF sensitivity against relying upon widely-available EMR Protection Products to prevent the effects of EMF exposure. He noted that EMF sensitive individuals were reporting the opposite effect: people found their symptoms and/or sensitivity worsened. Specifically, severe “symptom relapses.” Dr. Carlo noted:

Bluetooth allows your phone to communicate with other devices, such as the hands-free option in your car or your printer. If accessed by someone else though, they could misuse it to access your information or intercept your calls. Turn off the Bluetooth on your phone and turn it on only when you need to connect with other device. Many phones also allow users to set passcodes or additional security levels on their Bluetooth as well. Use all available options to increase your privacy.

In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
